Question

当我使用lein new PROJECT创建一个新项目然后从内部调用lein repl时，我得到以下异常：

Exception in thread "main" java.lang.ExceptionInInitializerError
    at clojure.main.<clinit>(main.java:20)
Caused by: java.lang.IllegalStateException: Attempting to call unbound fn: #'clojure.core/refer
    at clojure.lang.Var$Unbound.throwArity(Var.java:43)
    at clojure.lang.AFn.invoke(AFn.java:39)
    at clojure.lang.Var.invoke(Var.java:415)
    at clojure.lang.RT.doInit(RT.java:460)
    at clojure.lang.RT.<clinit>(RT.java:329)
    ... 1 more
Exception in thread "Thread-4" clojure.lang.ExceptionInfo: Subprocess failed {:exit-code 1}
    at clojure.core$ex_info.invoke(core.clj:4327)

知道可能会发生什么吗？我的项目在当天早些时候工作正常。

谢谢！

Answer 1

也许一个有效的例子可以帮助发现问题：

arthur@a:~$ lein new PROJECT
Project names containing uppercase letters are not recommended 
and will be rejected by repositories like Clojars and Central. 
If you're truly unable to use a lowercase name, please set the 
LEIN_BREAK_CONVENTION environment variable and try again.

arthur@a:~$ LEIN_BREAK_CONVENTION=true lein new PROJECT
Generating a project called PROJECT based on the 'default' template.
To see other templates (app, lein plugin, etc), try `lein help new`.
arthur@a:~$ cd PROJECT/
arthur@a:~/PROJECT$ lein repl
nREPL server started on port 47462
REPL-y 0.3.0
Clojure 1.5.1
    Docs: (doc function-name-here)
          (find-doc "part-of-name-here")
  Source: (source function-name-here)
 Javadoc: (javadoc java-object-or-class-here)
    Exit: Control+D or (exit) or (quit)

user=> Bye for now!arthur@a:~/PROJECT$ 
arthur@a:~/PROJECT$ lein version
Leiningen 2.3.4 on Java 1.7.0_40 Java HotSpot(TM) 64-Bit Server VM
arthur@a:~/PROJECT$

您使用的是lein 2.3.x +吗？如果没有尝试lein升级
您是否在正确的目录中运行lein repl？
lein deps是否成功下载了所需的一切？
lein版本工作（即：leiningen完全坏了）如果它不起作用，删除〜/ .lein并再次运行它。

最后，我删除了maven存储库（~/.m2）中的Clojure核心jar文件。当我再次推出这个项目时，莱宁根拉下了罐子，一切正常！其中一个文件必须以某种方式损坏：/
